2 Claims.

This invention relates to razor blade sharpeners.

It is an object of the present invention to provide a razor blade sharpener which has a rigid frame construction for containing a slide and side portions including a sharpener piece which will be engaged each time the slide is slid from one end of the frame to the other.

It is another object of the present invention to provide a razor blade sharpener having a slide which will alternately cause the sharpening of opposite sides of the blades as the slide is respectively moved first in one direction and then in the opposite direction.

Other objects of the present invention are to provide a razor blade sharpener which is of simple construction, inexpensive to manufacture and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a top perspective view of the razor blade sharpener embodying the features of the present invention.

Fig. 2 is a side elevational view of the sharpener shown in Fig, 1.

Fig, 3 is a perspective view of the slide with the cover part raised to permit the insertion of the blade or the removal of the same from the slide.

Fig. 4 is an illustrative view showing the blade in engagement with the sharpener pieces and free of the slide.

Fig. 5 is a transverse cross-sectional view taken generally on line 55 of Fig. 4.

Fig. 6 is an illustrative View showing the razor edges being drawn across the sharpener pieces.

Fig. '7 is a side elevational view of the diagonally ground sharpener pieces.

Referring now to the figures, If! and II represent guide rods over which a slide I2 is operated. The opposite ends of the guide rods Ill or II are embedded in end pieces l3 and M which may be made of plastic or other suitable material. At the opposite sides of the guides I and I2 are thin strips l and I6 which extend from one end piece to the other and is embedded in the pieces l3 and It to be rigidly retained between the same. The slide 12 includes a bottom part I! having holes therethrough for receiving the guide rods Ill and II and a cover or hinged part I8 fixed to the main part I! to be pivoted over the top of the same and upon a blade I!) to retain the same in place. The part I! has a central raised shelf portion 2| for receiving the blade I9 and extending upwardly from the shelf portion 2| are pins 22 over which the blade is extended. These pins 22 enter holes 23 in the cover [8 as the cover is brought downwardly over the blade IS. The cover I8 also has a central raised portion so as to lie flat upon the blade I9 and whereby the sides of the blade or the cutting edges thereof will extend outwardly from the portions 2! and 24 in order that they will be brought to bear upon sharpener pieces 25 carried on the strips l5 and I6. There are two sharpener pieces 25 so that simultaneously both edges of the blade will be sharpened at the same time. The sharpener pieces as shown in Fig. '7 are diagonally ground or formed or twisted so that as the blade I 9 is drawn first in one direction it will be drawn first over the top of the sharpener piece and then on its return movement will be drawn across the bottom of the sharpener piece. The strip pieces I5 and IE will give a little under the pressure of the blade or will twist slightly so that the sharpener pieces will be adapted to the blade edges being sharpened.

The top of the end piece i3 has a finger or thumb opening 21 and roughened portions 28 to provide a good grip by the thumb and fingers of the hand. The slide I2 has a thumb or finger opening 29 and also roughened portions 3!.

While various changes shall be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

l. A razor blade sharpener comprising guide rods transversely spaced from one another, end pieces connected to the opposte ends of the guide parts, a slide adapted to be extended over the guide rods and having separable parts, means projected from the parts for retaining the razor blade so that its edges extend laterally therefrom and are accessible from both bottom and top sides, thin spring strips extending from one end piece to the other and located respectively upon opposite sides of the guide rods, and sharpener pieces carried upon the spring strips and adapted to be engaged by the opposte side edges of the razor blade as the same is moved back and forth along the guide rods.

2. A razor blade sharpener comprising guide rods transversely spaced from one another, end pieces connected to the opposite ends of the guide rods, a slide adapted to be extended over the guide pieces being longitudinally diagonaliy ground whereby first one side of the blade edge will be engaged by one face of th sharpener piece on movement of the slide in one direction and then the opposite face of the side edge of the blade will be engaged by the opposite face of the sharpener piece on the return movement of the slide and blade along the guide rods.
